Metro Review
b. Normally, pilots can directly access weather forecasters
(1) In some cases, USN or USMC forecasting has been
centralized to support outlying satellite detachments during
off-peak hours when a forecaster is not on duty
(2) Most USN and USMC stations are manned 24 hours with
observers maintaining a basic weather watch
NOTE: Observers can provide basic services, e.g., read
latest field conditions or read a TAF (terminal) report.
(3) For forecaster services, e.g., DD-175-1 updates or
extensions, the observer can act as an intermediary with
the Sub-Regional Forecast Center (SRFC) forecaster or
advise the pilot who to call
(4) Advise forecaster/observer of ETA when terminal weather
is requested
(5) A listing of the Subregional Forecast Centers (SRFC) can
be found in FLIP FIH
